S, Pb, and Sr isotope geochemistry and genesis of Pb-Zn mineralization in the Huangshaping polymetallic ore deposit of southern Hunan Province, China

摘要

The Huangshaping Pb-Zn-W-Mo polymetallic deposit, located in southern Hunan Province, China, is one of the largest deposits in the region and is unique for its metals combination of Pb-Zn-W-Mo and the occurrence of significant reserves of all these metals. The deposit contains disseminated scheelite and molybdenite within a skarn zone located between Jurassic granitoids and Carboniferous sedimentary carbonate, and sulfide ores located within distal carbonate-hosted stratiform orebodies. The metals and fluids that formed the W-Mo mineralization were derived from granitoids, as indicated by their close spatial and temporal relationships. However, the source of the Pb-Zn mineralization in this deposit remains controversial.
